or on/off and floating point control of dampers in HVAC systems. Actuator sizing
should be done in accordance with the damper manufacturer’s specifications.
The actuator is mounted directly to a damper sha
f
t up to 1.05” in diameter by means
of its universal clamp. A crank arm and several mounting brackets are available for
applications where the actuator cannot be direct coupled to the damper shaft
.
Operatio
n
The actuator is not
p
rovided with and does not re
q
uire an
y
limit switches, but is
electronically protected against overload. The anti-rotation strap supplied with the
actuator will prevent lateral movement
.
The GMB(X) series provides 95° of rotation and a visual indicator indicates position of
the actuator. When reachin
g
the damper or actuator end position, the actuator
automatically stops. The
g
ears can be manually disen
g
a
g
ed with a button on the
actuator cover.
The GMB
(
X
)
24-3... actuators use a brushless DC motor, which is controlled by an
Application Specific Integrated Circuit (ASIC). The ASIC monitors and controls the
actuator’s rotation and provides a digital rotation sensing (DR
S
